Hi Guys!
I've just pull a request!
The Stubs for FIO_SeekSkipFile (ff9ab050 or ff9ab784) and CancelDateTimer (ffabd838 or ff2bd838) are straight forward, so I uncommented them to reduce the circle of suspects.
To find the 4 GUI Stubs, I created a Timer Database with two Value Registers and References.
There seems to be two pattern.
1. 0xFF8
2. SetHPTimerAfterNow, SetHPTimerNextTick, SetTimerAfter, CancelTimer (sort Resgisters from small to big)
At the Beginning It's hard to get the SetTimerAfter, 'cause I need to pull battery out and sometimes I got Error 70, only to run the debug test.
SetTimerAfter: After a lot of Try and Error! There are two strong candidates ff86af64 or ff874a74. After that the CancelTimer is much easy. The second hard part to find SetHPTimerAfterNow (ff859638, ff86af64, ff86c7a0, ff86dd88)
So I hope It helps!
